Australia has no porn industry as such. The most we have are men's magazines that do end up featuring topless women, but there has never been any instance of flatchested or small breasted women being featured. It's all very standard.

No porn is made in this country and no porn is even allowed to be on any Australian based server.

Which means the most this is TRYING to do is to stop these images from coming from overseas... most of which come from the Internet.
